how to apply code?
i don't know how you should do it, but i can explain you how i do it. Video + faq will be below the list, at very bottom of this post.

If anyone wonder. I requested rights to edit GamerzHell9137's post to add new/missing stuff, but instead i was proposed with just making new thread by my self. So well here it is.

"b" next to a game region stands for "BETA". The hack works with minor issues.
"(P)" next to a game region stands for "PROBLEM" This game have at least 1 serious problem cause of 60fps - explanations to each game will be below game list.
Links to coeds i ZeroX4 updated/added lead to posts, and not to pastebin site. (SO YOU WILL NEED TO SCROLL DOWN POSTS SOMETIMES TO FIND CODE FOR GAME YOU ARE LOOKING FOR SINCE SOME PPL PUT MULTIPLE CODES IN 1 POST)

Ys Seven - IF 60fps cheat is enabled. In Abandoned Town of Edona. In room just before main boss Demonic Octopus Avari El you go to the ladder which is west from stone monument, and on this map you take south-east exit which leads to elevator room. You will encounter serious problem, which will make your party jump off elevator before it finish moving.
Resulting in leaving your party on same flor you activated elevator. (problem only occurs if you try to go up - going down with elevator will drop your party too but well you want to go down anyway)
SOLUTION - just disable 60fps cheat and enable 30fps cheat before activating elevator. (JUST DISABLING 60FPS CHEAT WONT HELP YOU NEED TO ENABLE 30FPS CHEAT)
Additional screenshots 1. Room just above boss 2. Elevator room

To apply cheat codes:

1. Go to 60 FPS Master List
2. Either browse with your eyes or press CTRL+F and search for game name
3. Click on region name next to game of your choice
4. Copy cwcheat code you need (whole code not single line)
5. Before next step, make sure you have cheats enabled (game settings > enable cheats or CTRL+T for lazy ones like me)
6. In ppsspp launch a game for which you just copied code
7. Now press escape, click cheats and click edit cheat file
8. Text file will open. (IF FILE CONTAINS ANY CHEATS ALREADY > press enter then press up), now either press CTRL+V or right click and paste. Now save that file with CTRL+S or File>Save.
9. Close text file and in ppsspp click cheats again and select FPS cheat u desire.
10. ENJOY!!!
